Dib u eegista KWS-DC200-10A 0-200V DC Tamarta, Awoodda, Awoodda Volt Ammeter Calibration

Waa kuwan dhowr siyaabood oo aad mitirkan ugu isticmaali karto:

• La socodka kaydka baytariyada: Nidaamyada qorraxda ee aan shabakadda ku xirnayn ama nidaamyada tamarta kaydka ah, mitirkani wuxuu la socon karaa heerka dallacaadda iyo caafimaadka kaydka baytari ee 12V ama 24V waqti-qaar ah.
• Dhisidda qor-feeraha isticmaalka tamarta: U isticmaal si aad u cabbirto soo jiidashada tamarta qalab gaar ah ama wareeg muddo ka dib (watt-saacadaha) si aad u fahanto waxtarkiisa.
• Abuurista bandhigga sahayda korontada ee miiska: Ku dhex-dar qalabka sahayda korontada ee DIY ee doorsooma si aad u bixiso akhrin cad oo sax ah oo ku saabsan danabka iyo hadda soo baxa.
• Horumarinta tijaabiyaha awoodda baytariga: Adoo ku xira culeys hadda joogto ah, waxaad u isticmaali kartaa sifada tirinta amp-saacadaha (Ah) ee mitirka si aad u cabbirto awoodda dhabta ah ee baytariyada sida unugyada 18650 ama baytariyada asiidhka leh.
• La socodka heerkulka: Thermistor-ka ku jira wuxuu kuu ogolaanayaa inaad la socoto heerkulka heatsinks-ka, baytariyada, ama xirmooyinka, taasoo ka dhigaysa mid ku habboon mashruuc awood sare leh oo u baahan maareyn kulayl.

Guudmarka Qalabka

KWS-DC200-10A waa mitir dhijitaal ah oo isku dhafan, oo gudaha lagu rakibo. Qaybta dib-u-eegista waa nooca 10-ampere, kaas oo isticmaala resistor shunt gudaha ah si uu u dareemo hadda. Xirmada waxaa ku jira mitirka laftiisa, buug-gacmeed isticmaale oo leh jaantusyo fiilooyin faahfaahsan, iyo thermistor akhrinta heerkulka. Unuggu wuxuu ku shaqeeyaa sahay gaar ah oo 8-120V DC ah, halka uu cabbiri karo danab nidaamka 0-200V DC. Kala-soociddani waxay u oggolaanaysaa dabacsanaan, gaar ahaan marka la cabbirayo danabyo hooseeya.

Xagga hore, bandhig LED oo dhalaalaya ayaa muujinaya dhammaan cabbirada muhiimka ah: Danab (V), Hadda (A), Awood (W), Tamar (Wh), Awood (Ah), iyo Heerkulka (°C). Hal badhan oo riix ah oo xagga hore ku yaal ayaa wareejiya qaababka bandhigga kala duwan. Xagga gadaal, waxaad ka heli doontaa xariijimaha tamarta/cabbirka ugu muhiimsan, isku-xirka thermistor-ka, iyo laba potentiometer oo yaryar oo loogu talagalay in lagu hagaajiyo akhrinta danabka iyo hadda. Waxa kale oo jira badhan dib-u-dejin, in kastoo shaqadiisa la ogaaday inay tahay mid aan joogto ahayn qaybtan dib-u-eegista.

Hagaha Fiilooyinka

Fiilooyinka mitirkani waa kuwo toos ah laakiin waxay leeyihiin dhowr qaabab muhiim ah oo ku xiran qaabkaaga. Mitirku wuxuu leeyahay saddex fiilo oo aasaasi ah: fiilo cas iyo madow oo loogu talagalay sahayda korontada ee mitirka laftiisa (8-120V DC), iyo fiilo jaalle ah oo lagu cabbiro danabka nidaamka.

Qaabka 1: Cabbirka Baytari Danab Sare (8V-120V) oo aan lahayn Awood Dibadeed

Haddii danabka baytariga ama nidaamka aad cabbirayso uu u dhexeeyo 8V iyo 120V, waxaad si toos ah uga shaqayn kartaa mitirka isha. Xaaladdan, fiilada cas ee mitirka waxay ku xiran tahay xariijimaha togan ee baytariga, iyo fiilada madow ee taban. Fiilada jaalle ee dareenka danabka ayaa sidoo kale ku xiran xariijimaha togan. Culeyska waxaa lagu xiraa si taxane ah waddada hadda ee mitirka.

Qaabka 2: Cabbirka Baytari Danab Hooseeya (0V-8V) oo leh Awood Dibadeed

Marka la cabbirayo nidaam ka hooseeya 8V, mitirku wuxuu u baahan yahay sahay koronto oo gaar ah (8-120V DC) si uu u shaqeeyo. Qaabkan, fiilooyinka cas iyo madow waxay ku xiran yihiin sahayda korontada ee dibadda. Fiilada jaalle ee dareenka danabka waxay ku xiran tahay xariijimaha togan ee baytariga aad cabbirayso. Waddada hadda waa isku mid: togan ee baytariga wuxuu tagaa gelinta hadda ee mitirka, iyo culeyska ayaa ku xiran soo-saarka hadda.

Qaabka 3: Isticmaalka Shunt Dibadeed (noocyada 50A, 100A, iwm.)

Noocyada waaweyn ee mitirkan (50A, 100A) waxay isticmaalaan resistor shunt dibadeed. Xaaladdan, shunt-ka waxaa la dhigaa waddada soo-noqoshada taban ee wareegga. Fiilooyinka dareenka danabka ee mitirka ayaa ku xiran shunt-ka si ay u cabbiraan hoos-u-dhaca danabka, kaas oo u dhiganta hadda. Fiilooyinku waxay yihiin kuwo wax yar ka duwan oo si cad loogu qeexay buug-gacmeedka ku jira. (fiidiyowga 07:07)

Waa muhiim in la xusuusto in sahayda korontada ee gudaha ee mitirku aysan qaadi karin wax ka badan 120V. Haddii aad cabbirayso nidaam ka sarreeya 120V, waa inaad isticmaashaa sahay koronto oo dibadeed si aad u shaqaysiso mitirka laftiisa. (fiidiyowga 09:32)

Tijaabinta iyo Hagaajinta

Dibintidu waxay ku lug lahayd tijaabinta mitirka iyadoo la adeegsanayo koronto sii kordhaya iyo culeys elegtarooni ah. Akhrinta danabka ayaa la ogaaday inay aad u sax tahay, iyadoo la mid ah danabka la geliyay si ku dhawaad dhammaan. Akhrinta hadda ayaa sidoo kale aad u sax ahayd, iyadoo oo kaliya qadar yar oo 20-30 milliamps ah oo ka baxsan marka hadda uu sarreeyo (tusaale, muujinta 8.08A markii 8.00A la soo saaray), taas oo ah qalad aan la xisaabin karin. (fiidiyowga 11:44)

Mitirku wuxuu kaloo leeyahay sifo isku-darka "Wh" (Watt-saac) iyo "Ah" (Amp-saac), kaas oo tiriya wadarta tamarta iyo kharashka la isticmaalay muddo ka dib. Cutubku wuxuu si guul leh u sii hayay qiimayaashan xitaa ka dib markii si buuxda loo damiyay oo dib loo shiday. (fiidiyowga 14:06)

Haddii aad ogaato in akhrinta ay tahay mid wax yar ka qaldan, waxaad kalibrayn kartaa mitirka adigoo isticmaalaya labada potentiometer ee yar ee dhabarka ku yaal. Kan ugu dhow shunt resistor-ka ayaa hagaajiya akhrinta hadda, kan kalena wuxuu hagaajiyaa danabka. Adigoo si taxaddar leh u wareejinaya qodobbadan yaryar, waxaad si fiican u hagaajin kartaa bandhigga si uu u waafajiyo tixraac la yaqaan. (fiidiyowga 19:54)

Kala-bixinta iyo Qaybaha Gudaha

Furitaanka mitirka waxaa soo baxaya PCB si fiican loo dhisay oo xirfad leh. Qaybaha ugu muhiimsan waa microcontroller-ka Nuvoton MS51FB9AE, kaas oo u shaqeeya sida maskaxda qalabka, iyo op-amp-ka H6203 ee lagu hagaajiyo calaamadaha. Shunt resistor-ka gudaha waa qayb weyn oo 0.05-ohm (5 milliohm) ah oo loogu talagalay inuu qaado dhammaan 10A ee hadda. (fiidiyowga 16:36)

Cutubka dib-u-eegista wuxuu lahaa dhibaato yar halkaas oo badhanka dib-u-dejinta ee dhabarka uusan u shaqayn sidii la filayay, inkastoo faallo laga soo qoray website-ka uu soo jeedinayay inuu shaqeeyo. Tani waxay u badan tahay cillad gaar u ah cutubkan. Guud ahaan, tayada dhismuhu waa mid aad u fiican, iyadoo leh alxan nadiif ah iyo isku-ururin xirfad leh. (fiidiyowga 18:32)

Mashruuc Toos ah / Banaanbax

Banaanbax toos ah, mitirka waxaa lagu xiray koronto 12V ah iyo culeys elegtarooni ah oo loo dejiyay inuu soo saaro 5A. Mitirku wuxuu si sax ah u muujiyay 12.2V iyo 5A, isagoo xaqiijinaya waxqabadkiisa dhabta ah. Banaanbaxa ayaa sidoo kale muujiyay awoodda mitirka uu u leeyahay inuu la socdo isticmaalka tamarta muddo ka dib, isagoo muujinaya wadarta watt-saacaha iyo wakhtiga shaqada. Tani waxay ka dhigaysaa qalab wax ku ool ah oo lagu kalsoonaan karo mashruuc kasta oo u baahan kormeerka danabka DC ee saxda ah. (fiidiyowga 20:36)
